This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $370,747 to the University of California, Davis to conduct research focused on improving acid mine drainage (AMD) bioremediation. The overarching goal is to unravel the controls on the rate of iron removal by microbes in AMD and determine if subsurface iron reduction undermines these processes. The researchers will systematically link geochemistry and microbial metabolic potential to iron oxidation rate, examine the biogeochemical processes in the AMD subsurface, and assess the feasibility of seeding microbial communities to enhance bioremediation efficacy. The award also includes plans to develop an undergraduate research experience and data-rich teaching modules. This award runs from September 1, 2024 through August 31, 2027.
